2 Claims.

This invention relates to an air conditioning system for homes and more particularly to. an apparatus for washing, moistening and tempering the air.

The main object is to provide means to raise a spray and confine the spray Within a given area without splashing.

Another object of the invention is to provide a high speed rotating spray wheel to scoop upv a supply of water and by centrifugal force cause the water to turn into a line mist or spray.

Other objects will appear as the disclosure progresses. The drawings are intended to merely indicate a possible embodiment of the invention. it is obvious that the actual needs of manufacture may necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated but rather to denne such limits in the appended claims.

In the drawings Figure 1 is a side View, partly in section, showing the air conditioning apparatus.

Figure 2 is a section on line 2-2 of Figure l.

Figure 3 is an enlarged fragmentary View of the 25 spray wheel.

Figure 4 is a section on line 4 4 of Figure 3.

Figure 5 is an enlarged View of the drain outlet operating assembly.

Figure 8 is a fragmentary front view of the ioat 30 operated stem.

Referring now to the drawings in detail, numeral l designates the casing of the air conditioning apparatus, 2 the raw air inlet and 3 the conditioned air outlet. Mounted within the cas- 35 ing are a plurality of vertically disposed ducts l and 5 containing high speed fans 6 and l. The upper portions of the ducts are provided with side openings S and 9 for the air to enter and the lower ends are open as at Iil and II to allow the 40 air to pass out over a supply of water. The fans are mounted on the shaft I2 and driven by the motor I3 by the way of the belt I4.

At the bottom of the casing is a rotating spray Wheel I 5 mounted on the shaft I 6 and driven from 45 the shaft I 2 by the way of the belt I'I and arranged to partially dip in the supply of water I8 at the bottom of the casing. On both sides of the dipped portion of the spray wheel is a trough I9 arranged to prevent the water from 50 splashing sideways as the said wheel revolves. The spray wheel is constructed of a plurality of circular plates 2S, 2l and 22 held together by any suitable means and provided with a bulged out circular rim 23 near the periphery. Cut in this i5 rim at spaced intervals are a plurality of angular disposed ears Eni. As the spray wheel revolves anti-clockwise the ears will scoop up a certain amount of water which will enter the interior 25 of the rim 23 and due to the centrifugal force the water will leave the interior lets 2t into the atmosphere in the form of a Wall ci fine mist.

Ninneral 2l represents a water inlet pipe, 28 the water outlet pipe and 29 the oat operated valve to regulate the amount of water in the reservoir 323 formed in the bottom of the casing I. The float valve can be of the usual standard construction with the customary oat 3l at the end ci the lever 32 which is adapted to shut ofi the fr supply when the water reaches a predelevel. At the inner end oi the outlet pipe 33 is a hinged valve 35i spring pressed against the mouth of the outlet pipe 33 by the spring 34a. At the lowermost portion of the valve is a lip 35 to which is attached a rod 36. The upper end of the rod is slotted as at 3l for straddiing the iioat valve lever Numeral 33 designates a cable attached to the rod for manipulating the valve. The cable runs to the exterior of the casing and can be manually or automatically operated.

rlhe operation oi the apparatus is as follows:

The raw air is drawn in through the inlet 2 by the high speed fans t and l and then blown down through the ducts t and Si and over the supply of water i8 where it is given a preliminary treatment by washing out most of the foreign matter and impurities. The treated air then passes upwardly into the chamber 3i! as noted in Figure 1 through the spray or mist d@ and thence downwardly into the chamber il and next upwardly by the coils i2 and 'i3 and lastly outwardly through the outlet s into the rooms being air conditioned.

According to the way this apparatus is constructed the air must pass directly through the spray or mist 40 and thus be thoroughly cleansed and conditioned. The coil l2 is a heating coil and the coil i3 is a cooling coil. Thus if it is desired to heat the air entering the rooms the coil 42 is turned on and the coil 43 is turned oli. Vice versa if it is desired to cool the air the coil 42 is turned oi and the coil i3 turned on. In the event it is found that the air entering the rooms contains too much moisture the spray 49 can be shut ofi by simply pulling on the cable 38 which will open valve 313 and allow the water to pass out through the outlet 33 and thus reduce the water level below the spray wheel. It will be obvious that if the water level is lowered below the spray wheel it will be unable to pick up through the out' any water. The cable can be manipulated manually or automatically. In the event the valve 29 commences to leak Which will cause the Water level to rise above safe limits the float 3| will automatically rise and lift the rod 36 and open the valve 34 thus allowing the excess water to float out before it does any damage.

Having described our invention we claim:

1. In a device of the class described, a casing containing a supply of-wateiga spray wheel within said casing for forming part of the water into a spray, said spray wheel having a bulged out circular rim near the periphery of the Wheel to hold a supply of water and provided `with a plurality of inlet holes, ears bent upwardly from the edges of said holes for scooping up the water, and means to allow the supply of water to leave said circular rim under the influence of centrifugal force, said means comprising outlets adjacent said holes and leading from said rim to the periphery of said Wheel.

2. In a device of the class described, a casing containing a supply of water, a spray wheel within said casing for forming part of the water into a spray, said spray wheel mounted in said casing and partially dipping in said water, a bulged out circular rim near the periphery of the wheel to hold a supply of water and provided with a plurality of inlet holes, ears bent upwardly from the edges of said holes for scooping up the water, means to allow the supply of water to leave said circular rim under the influence of centrifugal force, said means comprising outlets adjacent said holes and leading from said rim to the periphery of said wheel, and a trough straddling said spray Wheel.
